Contribuição sôbre a origem da leucocitóse após administração de acetilfenilhidrazina

Os autores procuraram verificar a influência dos granulos de HEINZ no desenvolvimento de leucocitóse após injeção de acetilfenilhidrazina em animais. Injetaram dóses elevadas (70 mg. p.q.c.) em animais de grande pórte e em seguida no 5.° dia retiraram por sangria á branco o sangue do animal, hemolisaram e lavaram os granulos assim obtidos com solução fisiológica. O material conseguido por esta fórma foi injetado em cão de pequeno pórte, para obter-se uma alta concentração na circulação. Os resultados foram os seguintes: Cão 353. No dia 0 contava 8.900 leucocitos por mm3. Injetamos na veia 50 cm3 de soro fisiológico contendo granulos. No dia seguinte apresentava 20.000 leucocitos por mm3. Injetamos 80 cm3 na mesma via de solução de granulos, havendo o número de leucocitos caido para 16.800 por mm3. No 6. ° dia da prova o número de leucocitos retornava ao valor normal. Cão 350. No dia 0 leucocitose de 16.000 leucocitos por mm3. Injeção de 35 cm3 de solução de granulos elevou-a para 35.800 por mm3. Nova injeção no dia 2 apos o número de leucocitos haver descido para 23.000 por mm3 elevou-se para 31.000. No 6. ° dia, da mesma fórma que na experiência anterior, o número de leucocitos mostrou-se próximo a cifra do dia 0. Quando o número e normal, o aumento, após injeção dos granulos de HEINZ, e cerca de 3 vezes aquele número, ao contrário, quando inicialmente a cifra é elevada o aumento de leucocitos é unicamente de 1.2 vezes.

Alzinar amb marfull o pineda?: estudi comparatiu de 6 zones geobotàniques del parc del Castell de l'Oreneta

S’ha estudiat la vegetació actual del parc de l'Oreneta, l’únic de Barcelona en el qual es conserva en part la vegetació natural que hi havia abans de la seva destinació com a parc. L’objectiu és veure com l'impacte antròpic ha modificat la que segurament era la vegetació natural de la zona - un alzinar amb marfull empobrit- per una pineda de pi blanc. A més, s’analitza les diferents adaptacions de la vegetació del parc als factors del biòtop, i molt en particular del marfull i l'aladern. S’ha començat estudiant els factors ambientals propis del parc. Posteriorment, s’ha dividit el biòtop del parc de l'Oreneta en sis zones de vegetació amb característiques específiques estudiant-ne les espècies existents, els índexs de diversitat de cada zona, l'abundància de les espècies, etc.

Es presenta un resum dels resultats dels assaigs d’avaluació de varietats de blat de moro de cicle 700 i 600, obtinguts en la zona litoral de Girona, en el marc de la Xarxa d’Experimentació de Varietats de l’IRTA. S’han assajat híbrids convencionals i transgènics derivats del MON810, que incorporen resistència als barrinadors. Amb els resultats de quatre anys d’assaig han destacat principalment les varietats HELEN, ELEONORA, TIETAR, PR32R42, ASTURIAL i PR33P66, sense diferències significatives entre elles. Les varietats transgèniques s’han assajat un màxim de tres anys havent mostrat algunes d’elles una alta productivitat. Entre aquestes han destacat PR32P76, DKC6575, PR33P67 i HELEN Bt, si bé sense diferències significatives amb el testimoni ELEONORA. També amb els resultats de tres anys d’assaig cal remarcar la varietat de blat de moro convencional PR32W86, que ha mostrat un nivell productiu similar a les millors transgèniques. Amb només dos anys d’assaig ha destacat principalment la varietat transgènica BELES SUR.

A surgery for American cuteneous and visceral leishmaniasis among 1,342 dogs from areas in Rio de Janeiro (Brazil) where the human diseases occur

There are areas in the periphery of Rio de Janeiro city where human cases of Visceral and/or Cutaneous Leishmaniasis occur. The parasites have been identified as Leishmania donovani and Leishmania braziliensis braziliensis respectively. A survey for Leishmaniasis was done among 1,342 dogs from those areas using an indirect immunofluorescent test. From the dogs, 616 came from areas where only human cases of Visceral Leishmaniasis occurred, 373 from an area where all human cases were of Cutaneous Leishmaniasis and 353 from a third area (Campo Grande) where both visceral and cutaneous human cases were detected. The prevalence of parasite antibody titers among dogs from areas of Cutaneous Leishmaniasis was significantly higher than that of Visceral Leishmaniasis (8.6% vs. 4.3%, p < 0.02). The highest prevalence was observed among dogs from the area where both diseases are present (12.7%).

Pelvic floor dysfunction 6 years post-anal sphincter tear at the time of vaginal delivery.

INTRODUCTION AND HYPOTHESIS: This study aims to estimate fecal, urinary incontinence, and sexual function 6 years after an obstetrical anal sphincter tear. METHODS: Among 13,213 women who had a vaginal delivery of a cephalic singleton at term, 196 women sustained an anal sphincter tear. They were matched to 588 controls. Validated questionnaires grading fecal and urinary incontinence, and sexual dysfunction were completed by the participants. RESULTS: Severe fecal incontinence was more frequently reported by women who had sustained an anal sphincter tear compared to the controls. Women with an anal sphincter tear had no increased risk of urinary incontinence, but reported significantly more pain, difficulty with vaginal lubrication, and difficulty achieving orgasm compared to the controls. A fetal occiput posterior position during childbirth was an independent risk factor for both severe urinary incontinence and severe sexual dysfunction. CONCLUSIONS: Fecal incontinence is strongly associated with an anal sphincter tear. A fetal occiput posterior position represents a risk factor for urinary incontinence and sexual dysfunction.

Compartmentalized Cerebral Metabolism of [1,6-(13)C]Glucose Determined by in vivo (13)C NMR Spectroscopy at 14.1 T.

Cerebral metabolism is compartmentalized between neurons and glia. Although glial glycolysis is thought to largely sustain the energetic requirements of neurotransmission while oxidative metabolism takes place mainly in neurons, this hypothesis is matter of debate. The compartmentalization of cerebral metabolic fluxes can be determined by (13)C nuclear magnetic resonance (NMR) spectroscopy upon infusion of (13)C-enriched compounds, especially glucose. Rats under light α-chloralose anesthesia were infused with [1,6-(13)C]glucose and (13)C enrichment in the brain metabolites was measured by (13)C NMR spectroscopy with high sensitivity and spectral resolution at 14.1 T. This allowed determining (13)C enrichment curves of amino acid carbons with high reproducibility and to reliably estimate cerebral metabolic fluxes (mean error of 8%). We further found that TCA cycle intermediates are not required for flux determination in mathematical models of brain metabolism. Neuronal tricarboxylic acid cycle rate (V(TCA)) and neurotransmission rate (V(NT)) were 0.45 ± 0.01 and 0.11 ± 0.01 μmol/g/min, respectively. Glial V(TCA) was found to be 38 ± 3% of total cerebral oxidative metabolism, accounting for more than half of neuronal oxidative metabolism. Furthermore, glial anaplerotic pyruvate carboxylation rate (V(PC)) was 0.069 ± 0.004 μmol/g/min, i.e., 25 ± 1% of the glial TCA cycle rate. These results support a role of glial cells as active partners of neurons during synaptic transmission beyond glycolytic metabolism.

The use of the Internet now has a specific purpose: to find information. Unfortunately, the amount of data available on the Internet is growing exponentially, creating what can be considered a nearly infinite and ever-evolving network with no discernable structure. This rapid growth has raised the question of how to find the most relevant information. Many different techniques have been introduced to address the information overload, including search engines, Semantic Web, and recommender systems, among others. Recommender systems are computer-based techniques that are used to reduce information overload and recommend products likely to interest a user when given some information about the user's profile. This technique is mainly used in e-Commerce to suggest items that fit a customer's purchasing tendencies. The use of recommender systems for e-Government is a research topic that is intended to improve the interaction among public administrations, citizens, and the private sector through reducing information overload on e-Government services. More specifically, e-Democracy aims to increase citizens' participation in democratic processes through the use of information and communication technologies. In this chapter, an architecture of a recommender system that uses fuzzy clustering methods for e-Elections is introduced. In addition, a comparison with the smartvote system, a Web-based Voting Assistance Application (VAA) used to aid voters in finding the party or candidate that is most in line with their preferences, is presented.
